Boiler Room

About this Slot

Boiler Room is a mining-themed slot by Node Gaming with an RTP of 96%, high volatility and a maximum win of 5,282x. The game features 6 reels, 4 rows and 1024 ways to win. Matching symbols pay when three or more land on adjacent reels from left to right in any row position across the 1024 ways layout. The Flame Wild substitutes for every regular winning symbol except the Steam Valve scatter, helping to complete adjacent ways across the grid during both base play and bonus rounds. The Burn Cycles scatter lands anywhere on the grid and pays directly based on how many appear. Three or more Burn Cycles scatters trigger Meltdown Mode, which starts with 8, 10 or 12 cycles depending on the scatter count that launched the feature. Meltdown Mode progresses through a pressure gauge divided into named zones, each with its own multiplier. Winning spins raise the gauge by one zone while losing spins drop it by one, and the active zone's multiplier applies to all wins in that cycle. Three or more Burn Cycles scatters landing during the feature retrigger the mode and award 4 extra cycles. The Bonus option costs 100x total play and grants direct entry to Meltdown Mode starting in the Cold zone with standard +1 or -1 movement. The Super Bonus costs 500x total play, starts at Hot, gains 2 zones per win, drops only one on losses and can reach a 50x Meltdown multiplier with extra burn cycles. Super Boost costs 2x per spin and improves the trigger chance for Meltdown Mode until the feature lands or is toggled off. Hyper Boost costs 10x per spin and greatly increases the chance of triggering Meltdown Mode, remaining active until the bonus triggers or the player disables it.
